HOT-AIR REGISTER.

SPECIFICATION forming part of Letters Patent No. 657,049, dated August 28, 1900.

Application filed March 29, 1900. Serial No. 10,670. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE AUER, of To ledo, in thecounty of Lucas and State of Ohio, have invented certain new and useful Improvements in Hot-Air Registers; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in wallregisters particularly designed for use in connection with ventilating and hot-air heating apparatus; and the main object of the invention is to provide a hot-air wall-register having a swinging adjustable door or damper for the purpose of directing or deflecting all or any portion of the hot-air current into the room in which the register is located or passing all or any portion of the hot-air current into the room above. The door valve or damper may be used to entirely close the register when not in use.

Another object of the invention is to provide the register with an adjustable valve below the damper or door which can be used for regulating the flow of air to and through the register or for entirely shutting off same.

A further object is to provide means for ventilating the room by drawing cold air off the floor and through an opening in the register-casing into side lines or spaces exterior to the hot-air fines, thus in a simplernanner affording ventilation and at the same time preventing overheating of the woodwork adjacent to the hot-air fines.

The invention consists in the novel construction of the register and the combinations of parts therein, as hereinafter claimed, and the accompanying drawings illustrate a practical form of hot-air register embodying the invention, and I will describe the latter with reference to said drawings, wherein- Figure 1 is a front view of a wall-register embodying my invention. Fig. 2 is a vertical section therethrough on line 2 2, Fig. 1. Fig. 3 is a horizontal sectional view on line 3 3, Fig. 2, of one-half the register. Fig. 4 is a similar view on line t 4, Fig. 2, looking downward, of one-half the register.

Referring to the drawings, A designates the box or casing of the register, which is con- I slopes downwardlyand rearwardly from front to rear, as shown in Fig. 2, and is provided near the rear side with an opening a, over which is fitted a flue-section D, which is provided with side flanges d, secured by bolts to the top of easing A, section D being connected to a flue Q, which leads tothe upper room.

A grating F, which is preferably curved in cross-section, is supported in the casing A, as shown, its rear edge resting upon a ledge a on the back side of the casing and its front bar F resting upon the lower edge of the opening in the front wall of the casing and projects over a flange b, projecting from the inner face of the frame B above the air-chamber O, as shown. On this grating F are two upstanding flanges f, one at each end of the grating, which are provided with a series of notches f, in any one of which the lower end of an adjustable damper or door G may be placed. 'This door is of a size to close the opening in the front of the casing and in the frame B, as shown, and its upper edge engages in a recess formed between an offset A of the casing and the upper bar of frame B. This recess allows the door G to be slightly raised, so as to disengage its lower end from the notches f and then the door may be swung backward or forward into engagement A with any of the notches f, the door resting in the notches by gravity and being upheld in any position to which it is adjusted, from the closed position (shown in full lines, Fig. 2) to any intermediate position between that and the rearmost position, (shown in dotted lines G 2,) in which the door will ontirely close the opening a. By this means it is obvious that all or any part of the hot air entering the casing from flue P may be diverted into the room in which the register is located, or all or any part thereof may be passed through the casing directly into flue Q, or part of the air may be directed into the room and part be allowed to escape through the flue Q, according to the adjustment of the door or damper.G.-

As a further means for regulating the supply of hot air to and above the register or to enable the supply to be entirely out on, if deof the valve lI, so that by turningthis knob I the said valve may be thrown either into. the open position (shown in full lines, Fig. or to the closed position, (shown in dotted lines 1-1 in which position itsfreeedgebears against the ledge a on the rear side ofthe.

casing, and; the supply of hot air is entirely outoff. Obviously valveH may be also ad j usted to any intermediate position, so asto regulate the passage ofair to and" through the register-casing.

In the lower part of frame B is-a series of openings B communicating with theairchamber 0, and this chamber communicates at its ends with air-spaces O at opposi-tesides of the casing, which in turn communicate with air-spacesc exterior to the side of? the-- These air-spaces c-maybe continued up and around and exterior to the hot-air flue-- casin g.

Q, and this construction, therefore, will afford not only means for ventilating the room near the floor thereof, but the cold air'taken in through the chambers C and'ai'r-fiuesor spaces 0 and c'will prevent overheating of any combustible surfaces adjoining the hot;- air flues.

The operation of the devicewill be self-- evident from the foregoing description and drawings.

Among the advantages of this construction are that the amount of hot air enteringthe upper room may be controlled by either the door G or the valve H, or both, and again, that when the door G is fully opened, therebyshutting off all air from the flue-Q, the'amount of air entering the room in which=tlieregis+ ter is located can be regulated by. the valve H, or when door G is closed the amount of air admitted to flue Q can be regulatedby" valve H. Further, the ventilating-chamber below the hot-air opening I also'consider an important ad vantage in this class-of registers.

The register is very simple inconstruction,-.

andits parts may be cheaply cast and: easily assembled, and it also affords a very; efficient foot-warmer, whichis one of the-chief advantages of floor-registers.
